r9 290/390 give 29-30 mh/s while mining on Ubuntu. For a serious increase in performance, you have to use Ubuntu version no higher than 16.04 (with new Ubuntu kernels these cards have poor compatibility). You have to install driver version 17.40 and AMD SDK kit. Switching to Linux-like OS gives additional 10 mh/s (50%). There is a guide how to do it (in Russian): https://www.cryptoprofi.info/?p=3313. Ubuntu will be useful for mining on all old cards including R9 280, 290, 295 and 390.

I will give Ubuntu a try for these old cards. But how about rx 470 / rx 570? Will they also have higher hash rates with Ubuntu?

No, AMD has good drivers for RX cards for Windows 10.

Thanks for your reply. I will run rx470/580 with windows 10. And I will let r9 run with Ubuntu.
